I attended Armadillocon in July 2012. I spoke on the following panels:

Blogs, Twitter, Facebook, Tumblr (social media and writing)

Game of Thrones: The Book, the Series, the Impact

Pictures at an Exhibition (review of submitted artwork)

Building a Fictional Society from the Ground Up

Writing from a Viewpoint Other than Your Own

I also had a reading, and was gratified that some people showed up to listen! Best of all, my local writing group
critiqued the fourth book in my Torth series at the hotel bar.
We discussed my book from 11pm to 2:30am, and I got some great feedback and new ideas.
